94 s-10 4.3tbi vortec Posi?

How can I turn my crappy limited slip into posi? I've been told that a posi from a camaro or firebird will fit right in.

i had a 94 S10 SS that has a posi. try a junkyard

if you go to a junkyard, look on the RPO sheet in the glovebox for the code G80. that indicates a factory posi rear. the code before that (GU*) will tell you the gear ratio.
